Modern buildings, the ones built in the 21t century are a complex mix of functionality with abundance of support services like basement , podium for parking, play area at ground , and even terraces in common place. High rise buildings with multiple stack of wet areas like kitchen, toilets, and balconies. In commercial buildings large kitchen with cold stores, spas and more pose unique challenges especially if the services are not stacked linear (i.e) one above the other.
Commercial buildings with multiple functions pose greater challenge to diagnose the exact source of leakage. The solution is reverse PU injections which are carried out from source point and is extremely effective as it avoids breakages and can be carried out without having to shut down the commercial activities for longer duration of time.
PU INJECTION PROCESS INVOLVES:
1.Selection of point of treatment.
2.Drilling of holes in ceiling, wall fixing in the packers etc.
- Injection of the chemicals.
Care should be taken that the person carrying out this activity should wear all the necessary safety gadgets. Once this process is complete packers are not to be removed immediately to cater for second set of injections if required.
The treatment relies on the action of the chemicals with water and penetration thereto that helps in sealing the passageways through which the water moves from source of leakage point. One should involve an experienced waterproofing contractors in Mumbai for these works.
